Abstract: This paper analyzes the mechanism of electrical pulse blocking removing and stimulation, and introduces the application of electrical pulse blocking removing technology in the low permeability reservoirs in Shuanghe oilfield at high water cut development stage. It has been used in 6 wells/times, of which 5 wells/times have achieved good blocking removing effects, accounting for 83. 3% of the total. Filed application shows that electrical pulse blocking removing technology can effectively stimulate oil layers at medium - high water cut stages.
